“…TNF is mainly produced by activated mononuclear macrophages and is an essential inflammatory mediator. In addition, the research shows that CREBBP plays an important role in regulating gene expression and coordinating cell pathways in a series of activities such as embryonic development, cell regulation, adult nerve occurrence, and cognition [48] . Studies have shown a relation between heat shock proteins (HSPs) to activity such as cancer cell survival, proliferation, drug resistance, metastasis, and angiogenesis [49] .…”

Use Gas chromatography-mass spectrometry technology (GC-MS) to identify volatile chemical components in Ligusticum chuanxiong Hort. (LCH). The TCMSP and Swiss Target Prediction online platform were used to screen and predict the potential targets of the chemical components of LCH, and GeneCards, CTD, OMIM, DisGeNET, GEO databases were used to collect the potential targets of chronic cerebral circulation insufficiency (CCCI). A total of 50 volatile chemical components in LCH were analyzed and identified, and 126 potential targets for LCH treatment of CCCI were screened on this basis. Through further network topology analysis, 33 core components and 36 potential core targets were screened out. GO and KEGG enrichment analysis revealed that LCH played a therapeutic role through signaling pathways such as Neuroactive ligandreceptor interaction, Alzheimer disease, Pathways of neurodegeneration-multiple diseases, Proteoglycans in cancer, and Chemical carcinogenesis-receptor activation. The molecular docking results showed the top 4 active ingredients, Ligustilide, Terpineol, 3-Butylidenephthalide, and Linalool, and the top 5 core targets CREBBP, HSP90AA1, ESR1, VEGFA, and NR3 C1 all have good binding activity. The free energy is less than �-5 kcal/mol, and the molecular docking conformation is stable. LCH may improve the symptoms of CCCI by acting on inhibiting inflammatory factors, protecting nerve cells, and promoting angiogenesis pathways.

“…However, there is still not much experience with glueing deciduous wood species, especially for structural purposes (Král et al 2015, Todaro et al 2012). In addition, the behaviour of glued structural elements from selected species of deciduous trees were not as accentuated from the view of fire safety, as was the case, for example, with the current commonly used spruce wood (Chen et al 2017, Douglas 2004). From the point of view of drawing and high resistance to the action of biotic and abiotic factors, manufacturers are starting to apply oak wood, especially for load-bearing structures for the exterior.…”

“…Because of the concerns, it is highly recommended that appropriate protection is provided (Pitzner et al 2004;Mahnert and Hundhausen 2018). Fire resistance is another concern that should be considered very seriously due to significant increase in engineered wood usage in building construction (Chen et al 2017). The common practice for improving biological durability and fire resistance of wood products is impregnation with preservative and fire retardants, respectively.…”

The potential of improving wood preservative penetration into glued wood products bonded with one-component polyurethane by discontinuous adhesive bondline design

et al. 2021

As a vast majority of glued wood products are intended for outdoor use or for building construction, impregnation with different agents is important for ensuring proper performance. It has been shown that the impregnation prior to gluing has several disadvantages, therefore the possibility of carrying out impregnation after gluing is analysed in the present research. Impregnation efficiency as well as the effect on the bond quality is evaluated for the one-component polyurethane glued wood specimens. The results showed that the impregnation with Cu preservative after gluing did not affect the shear strength of the glued wood specimens, but did significantly restrict Cu preservative penetration due to the adhesive bondlines. Considering the results, the possibility of improving the impregnation efficiency was also investigated. By using specific adhesive application designs, which cover the bondline only partially, it was possible to improve the impregnation efficiency. However, the Cu distribution was inhomogeneous and the improvement was noticeable only up to the second bondline. The partial adhesive application design also affected the bond strength of glued wood specimens, which resulted in a decrease both in dry and wet state. However, the reduction was not so sever as to cause delamination during three consecutive wetting and drying cycles.
